Why does the computer LCD screen jump the screen, and what to do if the computer monitor jumps the s

This lz is not very detailed, computer frequency hopping, there are many factors. Graphics card overheating, LCD problems, driver problems, monitor cable problems, can cause frequency hopping, if LZ is playing frequency hopping, there is a high probability that the graphics card driver, or, the graphics card memory is too small.

In the process of using the computer, you often encounter the failure of the blue screen, black screen or blurred screen of the display, and the failure of the screen jump screen is not a few.

1. The refresh rate of the display is set too low: when the refresh rate of the display is set to be lower than 75Hz, the screen will often shake and flicker, and the refresh rate should be appropriately increased, such as set to be higher than 85Hz, and the phenomenon of screen shaking will generally not appear again.

2. The power transformer is too close to the display and chassis: When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Placing the power transformer away from the chassis and monitor will help you solve the problem.

3. Inferior power supply or power supply equipment has been aged: the workmanship and materials used in many miscellaneous computer power supplies are very poor, which is easy to cause the circuits of the computer to be poor or the power supply capacity can not keep up. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

4. The speaker is placed too close to the display: The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference phenomena such as screen shake and color crossing.

5. Viruses: Some computer viruses will disrupt the screen display, such as: character inversion, screen shaking, graphic flipping display, etc. The ubiquitous screen shaking scripts on the Internet are enough to make your head as big as a filial piety cow after being hit.

6. Poor contact of the graphics card: After reinserting the graphics card, the fault can be eliminated.

7. Win95 98 system after write cache. If this is the case, disabling all drive write-back caches in Control Panel - System - Performance - File System - Troubleshooter can resolve the problem at all.

The above are the reasons and solutions for computer monitor screen jumping, I hope it can help you.

The monitor refresh rate is set too low :

When the refresh rate of the display is lower than 75Hz, the screen often shakes and flickers, and the refresh rate is appropriately increased, such as setting it higher than 85Hz, and the screen shaking phenomenon generally does not appear again.

The power transformer is too close to the monitor and chassis:

When the power transformer is working, it will cause large electromagnetic interference, which will cause the screen to shake. Keeping the power transformer away from the chassis and display can solve the problem.

Inferior power supplies or power supply equipment that are aging :

The workmanship and materials used in many miscellaneous computer power supplies are very poor, which can easily cause the circuits of the computer to be poor or the power supply capacity can not keep up, and when the system is busy, the display will especially appear screen shaking. When the power supply equipment of the computer starts to deteriorate, it is easy to cause the same problem.

The speaker is placed too close to the monitor :

The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference phenomena such as screen shake and color crossing.

Viruses :

Some computer viruses can disturb the display of the screen, such as: character inversion, screen shaking, graphic flipping display, etc. The ubiquitous screen shake scripts on the internet are enough to make your head as big as a cow after a hit.

Poor contact of the graphics card:

After the graphics card is reinserted, the fault can be troubleshooting.

Win95 98 system after write cache caused by:

If this is the case, disabling all drive write-back caching in Control Panel - System - Performance - File System - Troubleshooter will resolve the problem at all.

Power supply filter capacitor is damaged

Open the case, and if you see the top of the power filter capacitor (the largest capacitor on the board) bulging up, then the capacitor is bad, and the screen shake is caused by a power failure. Once the capacitor is replaced, the problem can be solved.
